Shortwave infrared (SWIR) cameras are sensitive to shorter IR wavelengths between visible light and 3 µm. They've historically been used for qualitative imaging applications such as laser beam profiling, silicon wafer inspection, and imaging through layers of paint and ink. Now, with the addition of temperature measurement capabilities, SWIR cameras offer a win-win for anyone concerned with thermal analysis of high-temperature materials or processes.
Additive manufacturing technologies create components directly from a computer model, adding material only where needed. This article discusses how infrared cameras can help manufacturers find systematic problems and determine the changes needed to maintain product quality.
Finding and fixing hot spots within ever-shrinking electronic systems has become more and more difficult. This webinar examines close-up and microscopic lenses and how they allow infrared cameras to make accurate temperature measurements on components less than 25 µm in size and image targets as small as 3.5 µm.
Thermal cameras can allow many types of infrared measurements on the military test range. Depending on what you want to measure, you can choose the wavelength of the camera, the speed, the type of spectral filters and optics you want to use, and how much to spend. Here are some of the factors you should keep in mind when purchasing an IR camera.
Spatial resolution in any remote sensing device is measured in terms of the instantaneous field of view. It is an important consideration for IR cameras on the military test range that need to focus on far-away objects. Despite common misperceptions, zoom lenses work in IR cameras, but understanding spatial resolution is key.
